Abstract

It has been theorised that self-perception is integral to the regulation of exercise and production of an optimal performance. This concept has not been examined in an anterior cruciate ligament (ACL) reconstructed population where the consequences of injury and surgery may provide a substantive perturbation to perceptual capabilities. Ratings of perceived exertion (RPE) have previously been shown to enable prediction of exercise task duration (TD) during running and cycling activities in healthy individuals, but this has yet to be explored in intermittent and isolated muscle exercise that is typically utilised during resistance training and ACL rehabilitation. Accordingly, this thesis investigated: i) the relationship between self-perceived knee function and objective measures of musculoskeletal performance at a range of time-points across the ACL-rehabilitation period; ii) the relationship between two paradigms of self-perception (RPE; perceived TD) and TD in healthy individuals during an intermittent isometric fatigue task (IIF) under various conditions of increasing exercise stress.
